TWO-WH EELED VEHICLE.

SPECIFICATION forming part of Letters Patent No. 365,437, dated June 28, 1867.

Application filed November-19, 1886. Serial No. 2l9,407. (No model.)

To aZZ whom, it may concern:

Be it known that I, DANIEL W. HAYDOOK, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Inn? provement in Road-Carts, of which the following is a full, clear, and exact description, reference being had to the accompanyingdrawings, forming part of this specification, and in which Figure 1 is a side view of the part of a roadcart to which my device is applied. Fig. 2 is a bottom view of the same. Fig. 3 is a perspective View of the rear end of a thill and the fixed yoke in which it plays. Fig. 4- is a perspective .view of the spring, in which no novelty is claimed per 86.

The axle is shown'at 1, connected by clips 2 to the" lower parts of the elliptical springs 3.

The body 4 is secured to the upper parts of the springs .3.

'5 5 are brackets on the body, whose outer ends are formed into pivot-pins 6, which pass through eyebrackcts7, attached to the under sides of the thills 8. The thills have capacity for limited movement on the pins 6 as pivots.

9 is the cross-bar of the thills. The oscillatory movement of the thills is limited by yokes 10, which are fixed to the side of the body, and within which the rear ends of extensions 8 of the thills work. These ends carry a rubber buffer, 12, which surrounds a pin, 13, shown secured to the end of the shaft by tongue or tongues 14, the buffer being held on the pin by a nut, 15.

16 16 are spiral springs, arranged in pairs. Each spring is composed of a single bar' of steel, a part of which. is coiled in'a helix, 17,

and one end, 18, being given the form of a bracket. The other end forms an arm, 19, which i has an eye at the end to receive the clip-pin 20, that passes through the ears of the clip 21, by which the end of the arm is connected to the cross-bar. The two arms of the pair are con- M nected to the crossbar by a single pin, 20, and clip, 21, and the arms are also connected together nearer the helices bya clip, 22. The springs are secured to the body by the bracket-formed ends 18, as seen in Fig. 2.

The body is so balanced upon the axle that the springs 16 tend to hold the rear ends of extensions 8 of the thills centrallyin the yokes 10, so that the thills may move upward or downward with the horse without imparting any oscillation to the body, the springs 16 bending Without conveying the horse-mo tion to the body. x

I claim herein as new and of'my in vention- In a road'cart, the combination, with the body and thills having the splinter or crossbar 9, of spiral springs 16, having brackets 18,

secured to the floor of the body, and arms or'
